class beat.web.toolchains.models.Toolchain(id, sharing, name, version, short_description, creation_date, hash, previous_version, fork_of, author, declaration_file, description_file, errors)

DEFAULT_TOOLCHAIN_TEXT = '{\n "blocks": [],\n "datasets": [],\n "connections": [],\n "analyzers": []\n}\n'

declaration_file

The descriptor for the file attribute on the model instance. Return a FieldFile when accessed so you can write code like:

>>> from myapp.models import MyModel
>>> instance = MyModel.objects.get(pk=1)
>>> instance.file.size

Assign a file object on assignment so you can do:

>>> with open('/path/to/hello.world') as f:
...     instance.file = File(f)

description_file

The descriptor for the file attribute on the model instance. Return a FieldFile when accessed so you can write code like:

>>> from myapp.models import MyModel
>>> instance = MyModel.objects.get(pk=1)
>>> instance.file.size

Assign a file object on assignment so you can do:

>>> with open('/path/to/hello.world') as f:
...     instance.file = File(f)

errors

A wrapper for a deferred-loading field. When the value is read from this object the first time, the query is executed.

objects = <beat.web.toolchains.models.ToolchainManager object>

get_absolute_url()

get_api_update_url()

Returns the endpoint to update this object

get_api_share_url()

Returns the endpoint to share this object

get_new_experiment_url()

Returns the view to create a new experiment from self

save(*args, **kwargs)

Save the current instance. Override this in a subclass if you want to control the saving process.

The ‘force_insert’ and ‘force_update’ parameters can be used to insist that the “save” must be an SQL insert or update (or equivalent for non-SQL backends), respectively. Normally, they should not be set.
